Just wanted to say I will keep your husband and you in my prayers.
I had my left kidney removed in December '06. I didn't know there was anything wrong until I got a pain in my back when I tried to go to sleep. My husband took me to the hospital and they discovered a tumor and it was cancerous. I thought they were only going to take the tumor but they had to take the kidney too. I feel good and all my scans so far are good.
As a side note I had thyroid cancer too. I had my thyroid removed in September '06. They are not related so neither have spread.
Please let us know how he is doing....May God Bless!
